I checked my work and downloaded the the file. It plays ok on either the Nero player or the divx player but you have to drag and drop the file on the screen of the player for it to work. The file was run through the divx converter before uploading and came out as an mkv file. Plays fine otherwise
The Internet Archive can't produce derivatives of movies in the open-source Matroska (.mkv) file format. Windows users can play Matroska files in GOM player; Mac users can use the Perian plugin to play them in QuickTime. Linux users (and others) can use the VLC media player.
